Note: The Internet Explorer 11 desktop application will be retired and go out of support on June 15, 2022 (for a list of what's in scope, see the FAQ). The same IE11 apps and sites you use today can open in Microsoft Edge with Internet Explorer mode. Learn more here.

Symptoms

Consider the following scenario:

  • Internet Explorer 10 is installed on a computer that is running Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 SP1.

  • You browse to a website that prompts you to enter a user name and password to sign in.

  • You enter a user name and password, you configure Internet Explorer to save the credentials, and then you sign in to the website.

  • You preform one of the following operations:

    • You log off the computer and then log on to it again.

    • You restart the computer.

  • You browse to the website again.

In this scenario, you are prompted to enter a user name and password to sign in to the website.

Note The expected behavior is that you can sign in to the website without the website prompting you to enter a user name and password.

Cause

This issue occurs because the WinInet cache task is not notified to close when you log off or restart the computer.

Windows 7 and Windows Server 2008 R2 file information notes
Important Windows 7 updates and Windows Server 2008 R2 updates are included in the same packages. However, updates on the Update Request page are listed under both operating systems. To request the update package that applies to one or both operating systems, select the update that is listed under "Windows 7/Windows Server 2008 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each update applies to.

  • The files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    Version

    Product

    Milestone

    Service branch

    6.1.760
    1.18xxx

    Windows 7 and Windows Server 2008 R2

    SP1

    GDR

    6.1.760
    1.22xxx

    Windows 7 and Windows Server 2008 R2

    SP1

    LDR

  • GDR service branches contain only those fixes that are widely released to address widespread, critical issues. LDR service branches contain updates in addition to widely released fixes.

  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows 7 and for Windows Server 2008 R2" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintaining the state of the updated component. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
